Quick and dirty application that creates a movie showing pace, stroke
rate and other variables as recorded by ErgData from the monitor of your
Concept2 erg. Suitable for overlaying on a video. (almost) All done in-browser.
Quick test showing different stroke rate and pace combinations.
Coach wants to provide technique video and
show pace / stroke / distance / time information.
Athlete wants to compare old and recent technique sessions
simultaneously with pace / stroke / distance
/ time information.
Chrome web browser (or other Canvas- and WebKit-enabled browser).
Download that session from the logbook
as a CSV file (button at the bottom of the page).
Drag and drop that .csv file on the grey rectangle above.
Be patient. Wait until the status says Movie generation
Two faux-monitors will appear. Click the three dots from
the one on the right and choose Download.
Import that file into your video editing software, or if the format
isn't supported, use your chosen file conversion software to turn
the .webm file into a .mp4 or
similar for your movie software.
Import the resulting video into your video editing software
and go for gold.
How can I see other variables, like average pace?
The Concept2 format for .csv is limited to elapsed time, stroke
rate, instantaneous pace, distance, heart rate, watts and
calories per hour.
But you can calculate average pace (and others) from those variables!
Yup, this is on the list of things to fix.
The output video format sucks. Can you change it?
Yup, this is on the list of things to fix. If you have suggestions
please pass them along.
Why would I use this over <other software>?
This handles (almost) everything in-browser. Feel free to use something
else if this doesn't fit your needs.
Does this handle intervals?
It generates multiple movies for interval workouts!
Yup. The Concept2 .csv format doesn't include rest periods, so
the output movie is split into parts for easier overlaying.
Why are there pauses in the movie at the start of each interval?
Purely for allowing you to better sync the overlay in your editing
Why does this miss the first few and last few seconds of an interval?
The data provided on the Concept2 Online logbook for a session appears to
only include data on the stroke. This means the
first stroke and the end of the workout are typically missed.
The time and distance don't increase smoothly! WTF?!?
Yup; as stated above the Online logbook data appears to only include
data on the stroke, not between strokes.
So any pointers on how to sync this properly over video of me rowing?
The frame where the numbers change from zero should be synced
to match the end of your first (possibly
second) actual stroke. This is
because the rower / SkiErg won't necessarily register
your first stroke, espectially if you start
rowing from the main menu screen.
The last frame of numbers should be synced to
match the end of your last actual stroke.
Try syncing at the end of the overlay movie first, then lock in the
start stroke. Note that you may need to stretch either your video or
the overlay video to get 100% accurate overlay goodness. But
as a savvy video editing connoisseur, you already know that.
This doesn't work on my phone!
Not indended for phone use; try a computer instead.

This application has been tested and works using the latest version
of the Chrome web browser on
Mac OS X. YMMV on
